1.The most sincere, goodhearted, and gorgeous girl to grace the world with her lively presence. Some say she resembles Rachel Weisz but in actuality Weisz would never be able to reach the pedestal of beauty that Joanna sits atop of.

2. Pretty much the most awesome person you can ever hope to meet. Be weary though, Joanna is a complete badass and is known to carry either a nine or a gat with her at all times - for protection from other jealous rival badasses and if she just feels like being a thug and robbing a liquor store or grocery for the hell of it.

"Man you shot up and robbed five armored vans, assaulted three cops, and beat up Jean-Claude Van Damme. You're almost as badass as Joanna."

Perfection in human form. Someone who is "Joanna" is likely to be creative, lovely, intelligent and charming; and will always have an impeccable dress sense.
If you are friends with a Joanna, count yourself lucky. They are truely the nicest people you will ever meet.

Seriously the most awsome-est person ever
Most Joannas will typically be extremely successful in life and have some friends who like to copy off of them.
Joannas really don't like niners and usually bully them around in the lockers, some Joannas may even steal their lunch money....
Niners beware...
